The Micro Dispense Module realizes the precise dosing and metering of liquids in the microliter to milliliter range. The system is characterized in a modular design with connectible fluid in- and outlet, optional actuators and sensors for measuring flow rates.

The central element is a micro annular gear pump, a robust and highly precise device with an extremely long service life and low pulsation. The pump allows dispensing the smallest liquid amounts on the one hand and rinsing with high flow rates on the other.

The ARM Cortex M3 processor provides the necessary system intelligence for integrating sensors and pump into a closed loop control, monitoring the process-accurate dispense and enabling communication and programming. It can be addressed with the same programming commands than a syringe pump.

The , whose size corresponds to the half-height syringe pumps format, guarantees process reliable liquid handling both in new analytical devices as well as when replacing syringe pumps in existing systems and reduces the maintenance and service expenditures.
